Supply TI TPS23882EVM-008 Evaluation Module, Supply TPS23882 Eight-Port PoE PSE Daughter Card

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supply of [TI] TPS23882EVM-008: TPS23882 Class 3, 30W, 2-pair PSE daughter card for 8-port PSE systems. Product details are as follows:

The TI TPS23882EVM-008 daughter card, as an evaluation module specifically designed for 8-port PSE systems, offers an ideal tool for engineers to build efficient PoE system prototypes and accelerate product iteration. This is achieved through its Category 3 30W output capability, twisted-pair power delivery architecture, and comprehensive evaluation ecosystem.

I. Product Overview:
The TPS23882EVM-008 is an 8-channel PoE PSE daughter card based on the TPS23882 controller. Fully compliant with the IEEE 802.3bt standard, it supports Category 3 PoE power delivery with a maximum single-port output of 30W. Utilising a 2-pair power delivery method, it seamlessly accommodates Gigabit Ethernet data transmission requirements. The TPS23882EVM-008 sub-card is not a standalone unit. It must be used in conjunction with the TI BOOST-PSEMTHR8-097 motherboard, MSP430 LaunchPad development kit, and USB2ANY interface adapter to form a complete PoE evaluation system. This facilitates rapid functional verification, performance testing, and firmware development for multi-port PSE systems.

II. Comprehensive Evaluation Ecosystem:
A key strength of the TPS23882EVM-008 lies in its robust evaluation ecosystem. Each component fulfils specific roles, providing end-to-end support spanning hardware connectivity, data exchange, and firmware development. This ecosystem comprises the following critical elements:
TPS23882EVM-008 Sub-Board: The core functional carrier integrates one TPS23882 8-channel PSE controller. It features 200mΩ current sensing resistors, port status LEDs, user test points, and a reset button. Supporting single DC power input, each 2-wire pair port delivers stable 30W power output while incorporating comprehensive overcurrent and over-temperature protection mechanisms.
BOOST-PSEMTHR8-097 Main Board: A separately sold adapter board providing interfaces for the daughter card, power input (screw terminals), and peripheral expansion. It incorporates an on-board LM5019 buck converter capable of delivering a stable 3.3V output to power the daughter card's digital circuitry. Typical power consumption is 6mA, with a maximum of 12mA, ensuring stable system startup and operation.
USB2ANY Interface Adapter: Serves as an I²C communication bridge when used with the TPS23882EVM GUI, enabling data exchange between the computer and daughter cards. Supports parameter configuration, status monitoring, and data acquisition functions.
MSP-EXP430FR5969 LaunchPad: A development kit featuring the MSP430 microcontroller. When used with Code Composer Studio software, it enables firmware development, debugging, and programming for the TPS23882EVM-008, supporting custom power management strategies and protection logic.

III. Core Technical Features: Dual Assurance of Performance and Reliability
The exceptional performance of the TPS23882EVM-008 stems from the robust core of the TPS23882 controller and its optimised hardware design. Its core technical features encompass multiple dimensions including power delivery capability, detection and classification, protection mechanisms, and programmability, comprehensively meeting industrial-grade application requirements:
1. TPS23882EVM-008 High-Precision Power Delivery and Monitoring Capabilities
The daughter card supports IEEE 802.3bt Type-3 power delivery, delivering up to 30W per port. Programmable power limiting achieves ±3% accuracy, while the 200mΩ current sensing resistor enables 2% precision current sensing, ensuring stable and accurate power delivery. Each port incorporates a dedicated 14-bit integrated current ADC, enabling continuous current monitoring and parallel classification measurement. This not only provides real-time feedback on port operational status but also accelerates port turn-on speed, enhancing system response efficiency.
2. TPS23882EVM-008 High-Reliability Detection and Protection Mechanisms
Employing 4-point detection technology, it features robust main power source detection (MPS) with strong noise immunity. This accurately identifies legitimate PD devices, preventing false triggering and invalid power delivery. Concurrently, it supports traditional PD capacitance measurement, ensuring compatibility with legacy PoE equipment. Protection mechanisms include integrated surge and operational foldback protection, selectable current limiting (425mA/1.25A), and thermal shutdown (operating temperature range: -40°C to +125°C). These effectively address anomalies such as overcurrent, undervoltage, and overheating, safeguarding both the system and PD devices. Furthermore, 1-bit or 3-bit fast port shutdown inputs support priority control for efficient port management during emergencies.

IV. TPS23882EVM-008 Typical Application Scenarios: Addressing Multi-domain PoE Requirements
Leveraging its multi-port, high-power, and industrial-grade reliability features, the TPS23882EVM-008 evaluation solution is extensively applicable for developing various PoE PSE devices. Typical scenarios include:
Enterprise and Small Office Switches: The 8-port design caters to small businesses, branch offices, and SOHO environments. Its 30W power capacity simultaneously powers high-definition IP cameras, wireless APs, IP phones, and similar devices, while Gigabit data transparency ensures network performance.
Network Video Surveillance Systems: Provides a PoE power supply module prototype for NVR/DVR equipment, supporting integrated power delivery and data transmission for multiple high-definition cameras. This simplifies cabling complexity and enhances system stability.
Smart Building & Lighting: Compatible with smart ceiling LED switches, sensor nodes and similar devices. Its two-wire pair power architecture and flexible power configuration meet diverse lighting load and sensor device power requirements.
Wireless Backhaul & Small Cell Networks: Delivers stable PoE power to outdoor small cell base stations and wireless backhaul equipment. Industrial-grade wide-temperature design ensures resilience in demanding outdoor environments.
